Title: Method for producing a joint between glass tubes differing in melting point and co-efficient of expansion and composite glass tube obtained by this method
Inventor: RAAP BASTIAAN EVERARDUS BOL

Filed: 1952-07-22
Abstract: 698,667. Joining glass parts. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. July 22, 1952 [July 28, 1951], No. 18553/52. Drawings to Specification. Class 56. A method of producing a joint between glass tubes differing in melting point and coefficient of expansion by means of transition glasses the coefficients of expansion of which differ by practically equal intervals, is characterised' in that the tube with the higher melting point is formed into a test-tube having a very thin-walled bottom, after which a small hole is blown in the middle of the bottom and filled with a droplet of the first transition glass, after which the bottom is blown out a little, the same process being repeated for each next transition glass to be used, the tube having the lower melting point being attached finally to the last ring of transition glass, after which the joint is blown out to the desired diameter.

Title: Control members for aircraft
IPC: B64C13/00
Filed: 1928-06-28
Abstract: 316,395. Armstrong Whitworth Aircraft, Ltd., Sir W. G., Green, F. M., and Lloyd, J. June 28, 1928. Steering and balancing.-Aircraft control members are actuated e.g. by a pair of relay flaps pivoted about axes perpendicular to that of the member and mounted on interconnected arms adapted to move in opposite directions but to act in unison on the control member. Fig 6 shows two relay flaps 2 pivoted on vertical axes on arms 5 pivoted at 6, the arms being connected by cables to the ailerons so that equal movements of the arms 5 towards or away from one another effect normal movements of the ailerons. The relay flaps 2 are connected by parallel cables 9 to cross-shaped levers pivoted about the same axes as the levers 5 and connected by the cables shown to a handwheel 12. The use of two flaps ensures the balancing out of any disturbing effect due to side pressure thereon. The cables 9 may be passed over guide pulleys instead of being connected to levers but the flaps 2 would, in this case, not necessarily remain parallel to their initial setting.

Title: Process for the preparation of vinyl chloride polymer and copolymer compositions
IPC: C08J3/205
Filed: 1966-05-03
Abstract: Compositions of vinyl chloride polymer or copolymer containing stabilizers, plasticizers, lubricants, fillers, colouring, anti-oxidants and/or or anti-static agents are prepared by homogenizing the polymer and additive with a C1-C2 halogenated hydrocarbon, which is a nonsolvent for the polymer and is liquid during the homogenization but separable from the composition by degassing and removing this liquid by desorption to leave a granular product; specified media are vinyl chloride, methyl chloride, methylene chloride, ethyl chloride, methyl bromide, dichlorodifluoromethane, dichlorotetrafluorothane, trichlorofluoromethane and pentachlorofluoroethane.  The polymer may be a homopolymer or a copolymer with vinyl acetate or a mixture thereof or a mixture of homopolymer with a graft copolymer of butadiene and acrylonitrile on a P.V.C. base.  Specified additives are:  stabilizers, organic salts of tin, lead or alkali or alkaline-earth metals and epoxy soya oils; plasticizers, butyl, octyl and dodecyl sebacates, phthalates and adipates, decyl diphenyl phosphite and chlorinated paraffins; lubricants, stearic acid vegetable and synthetic waxes; fillers, carbon, calcium carbonate, rutile, anatase, silica and alumina; antioxidants, dibutyl paracresol.  In one embodiment vinyl chloride is partially polymerized in bulk, the additives are then added and polymerization continued; unreacted monomer which forms the organic medium is finally removed by degassing.

Abstract: 590,482. Fluid - pressure servomotor devices. BENDIX - WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Oct. 10, 1944, No. 19531. Convention date, Oct. 5, 1943. [Class 135] A fluid-pressure servomotor device, particularly for operating the throttle valve 5 of an engine 4, comprises a piston 19 in a cylinder 15 and a diaphragm 36 in a casing 35, both piston and diaphragm being coupled by rods 18, 48 and a lever 55 to an actuating rod 7 for the valve 5. The main actuation is by fluid-pressure, from an operator's control valve 21 to the cylinder 15 but the fluid-pressure is also supplied to the diaphragm chamber- 39 to provide an initial limited movement to the rod 7 in the event of friction momentarily holding up the piston 19 in its cylinder 15. The movement of diaphragm 36 is limited by stops 51 and 53 and is so proportioned that the increasing fluid-pressure will overcome the static frictional resistance of the piston 19 before the diaphragm abuts these stops. When this occurs the movement of piston 19 tends to return. the diaphragm towards its central position. Return movement of the piston 19 and diaphragm 36 is effected by a spring 11 on the rod 7 on operation of the valve 21 to release the actuating fluid-pressure.

Abstract: Synthetic zeolites are prepared by acid treating a montmorillonite clay, neutralizing the mix, washing with water, and heating the residue under reflux with a solution containing sodium-hydroxide and silica sol.  The acid treatment may be carried out under reflux with sulphuric or hydrochloric acid in a concentration of 1 to 40% by weight, the clay to acid weight ratio being between 0.1 and 4.0 and the zinc at the reflux temperature 1/2 to 24 hours. The neutralization is preferably carried out with ammonia and the residue is water washed until it is substantially salt free.  The residue may be suspended in a solution containing 15 to 35% by weight of NaOH and silica sol. containing 30% by weight of SiO2, between 700 and 900 g. of NaOH solution per 100 g. of clay and between 700 and 900 g. of silica sol. per 100 g. of clay being used and reflux being continued until crystallization is substantially complete. The product is a mixture of zeolites containing a high proportion of faujasite and zeolites of the chabazite-gmelinite series.  It may be used as a catalyst or catalyst support and with the incorporation of Group VIII metals, particularly platinum group metals, may be used as cracking or hydrocracking catalysts.
